If I try to delete I get a message telling me that the files are on a write-protected file system!
There is a purge command, but I don't know which. I thought it was automatic.
Can anyone help my understanding here?
Anton,
I'm not a btrfs expert, but windows ntfs has had conceptually similar
"shadow copy" functionality since windows 2003. I am expert on it.
With ntfs the shadow copies are maintained until the disk space is needed for existing files. When that happens, the oldest shadow copy is deleted automatically. There is nothing the user needs to do or even be aware of.
I'm curious. Is this different from the trash folder?
Ntfs shadow copies are totally unrelated to the trash folder. It is much more similar to lvm differential snapshots, but maintained within the filesystem. I don't know how btrfs does it, so I can't compare/contrast. Greg
